Node.js provides an equivalent of Java's Phaser synchronization construct through the worker_threads module. In Node.js, Phaser-like behavior can be achieved using a combination of Worker threads, MessageChannel, and other synchronization primitives such as Promise, AsyncFunction, or custom implementations.
Here's a simplified example demonstrating how you can achieve Phaser-like synchronization using worker_threads in Node.js:
// main.js
const { Worker, MessageChannel } = require('worker_threads');
class Phaser {
constructor(numWorkers) {
this.numWorkers = numWorkers;
this.barrier = new MessageChannel().port1;
this.workers = [];
}
arriveAndAwait() {
return new Promise(resolve => {
const worker = new Worker('./worker.js');
this.workers.push(worker);
worker.postMessage({ barrier: this.barrier }, [this.barrier]);
worker.once('message', () => {
resolve();
});
});
}
async waitForCompletion() {
await Promise.all(this.workers.map(worker => {
return new Promise(resolve => {
worker.once('message', () => {
resolve();
});
});
}));
}
}
const phaser = new Phaser(3);
async function run() {
for (let i = 0; i < 3; i++) {
await phaser.arriveAndAwait();
console.log(`Worker ${i + 1} has completed phase.`);
}
await phaser.waitForCompletion();
console.log('All workers have completed all phases.');
}
run();
// worker.js
const { parentPort } = require('worker_threads');
parentPort.once('message', (message) => {
const barrier = message.barrier;
setTimeout(() => {
// Simulate some work being done by the worker
console.log('Worker completed its task.');
// Signal that the worker has completed its task
barrier.postMessage(null);
}, Math.random() * 3000);
});
In this example:
main.js creates a Phaser class that emulates Phaser-like behavior. It creates a pool of worker threads and synchronizes their execution using message passing.
Each worker thread (worker.js) waits for a message from the main thread, then simulates some work and signals back to the main thread upon completion.
This implementation demonstrates how you can achieve Phaser-like synchronization in Node.js using worker_threads and message passing. Depending on your specific requirements, you may need to extend or customize this implementation further.
